Not going to vote just yet (I likely will sometime before the deadline if I remember to lol) since I want to give BigBlueFan a chance to go over his lineup and add things I may not say, but since my post admitting my wrongdoings in the other thread was well received, I'll comment on the teams...
PG: I think JHannibal's guys compliment one another very well. Payton is one of the best defensive point guards of all-time and could certainly score the ball some even if three point shooting wasn't his greatest strength. Price wasn't a great defender, but was a very good initiator and deadly outside shooter. Chris Paul is one of the better two-way point guards to play. Great ball handler, distributor, defender, outside shooter. Lillard's not a great defender, but he can take over a game when he gets hot.
SG: Mullin and Maravich are both great scorers, but far from the best defenders. That description fits both Ray Allen and Devin Booker as well. Hal Greer, I'm not entirely sure whether to put him in the shooting guard or point guard spot. I decided to put him in the shooting guard spot since he seemed to be more of a scorer, although he could be utilized as a secondary ball handler and had more of a point guard's body. Excellent player from back in the 60s who shouldn't be slept on.
SF: Giannis is being put as a small forward. That's fine. I consider him a positionless player. By 'positionless', I mean you don't have to confine him to any one position. You can also use him at either guard spot, the '4' spot or even as a 'small ball' center. About the only thing he doesn't do really well is shoot the ball from the outside, so it's a testament to him that he dominates despite of not being a prolific outside shooter. Butler is one of those athletic '3 and D' wings who obviously fits the modern game very well. I'm not sure what's happened to his outside shot recently, but he's been a strong shooter in the past. Alex English and Bernard King weren't as good on the defensive end as Giannis and Butler are, and both were a little like Giannis in that they weren't wonderful outside shooters, but they were walking buckets who could go out and get 30 or 40 in a game easily.
PF: Bird is being listed in this spot, but obviously I'd assume he'll play some at the '3' spot as well. I don't have to say a lot about him. He was a two-way force without a weakness in his game at his peak. Everyone's rankings can differ, but at worst, he's one of the top 10 players in NBA history. Having him as a small ball center is an interesting idea since I said Giannis could be one. I didn't think about Bird in the role, but I like the idea since he has the range to draw big guys away from the basket.
PF/C: I know Willis Reed is being listed at power forward, but he's interchangeable to me. Regardless, he was a terrific rebounder, defender and scorer at his best. Also a very tough player as Game 7 of the 1970 Finals can attest to. Pau Gasol, Dan Issel and AD are also interchangeable to me, so they're being put in this category along with Willis. Gasol really found his niche as the #2 guy with the Lakers complimenting Kobe. He can just be a strong defender/rebounder to provide some resistance against Wilt/AD/Issel and score when necessary on JHannibal's team. We're all Dan Issel fans on this board. His best pro years came in the ABA, but he was still a very productive player with the Nuggets into his mid-30s. Like going to the Lakers and teaming up with Kobe did wonders for Gasol, it's done the same for AD teaming up with LeBron in LaLa Land. He's still the same excellent two-way player, but he undoubtedly feels far less pressure to have to do everything in L.A. as I'm sure he felt he had to do with the Pelicans.
C: Now the true centers, Wilt and 'The Admiral.' In terms of statistical dominance, you could make a very strong case that Wilt is the NBA's all-time king in that regard. Nobody put up the point/rebound totals he did for a 5 or 6 year stretch. They even widened the painted area to try and make it harder for him, but he was still an unstoppable force. Outside of Bill Russell, very few could hold their own against Wilt. I think some people forget that he was also an underrated passer, averaging as many as 8.6 assists per season once. David Robinson was one of my favorites growing up, and obviously one of the best centers and players of the 1990s. He's not on Wilt's level, but had a strong all-around game of his own and certainly wouldn't back down against Wilt.
